Rechargeable Na/Cl2 and Li/Cl2 batteries
Na/Cl2 and Li/Cl2 batteries successfully turn the primary Li/SOCl2 battery into a rechargeable battery for the first time since its invention in the 1970s. Na/Cl2 and Li/Cl2 batteries operate based on the redox between either NaCl and Cl2 (Na/Cl2 battery) or LiCl and Cl2 (Li/Cl2 battery) and deliver a cycling capacity of up to 1200 mAh/g at room temperature and up to 5000 mAh/g at low temperatures down to -80   C with discharge voltage between ~ 3-3.5 V.
